How to Clean Fiberglass Tubs & Showers

While used for cleaning, often it can be surprising to find so much dirt in your fiberglass tub or shower. Fiberglass showers and tubs lend a durable and easy-to-care-for convenience to your bathroom, but like anything else, they need regular cleaning. Dirt that doesn't get rinsed away, soap scum, and hard water buildup can all leave your fiberglass tub or shower looking dingy. Cleaning it up is a simple task if you stay on top of it.

It's tough to feel clean in a dirty tub or shower.

Step 1

Wipe down the tub or shower stall with a damp sponge and soapy water. Liquid soaps are optimal for this task. Avoid any powdered detergents that may scratch the fiberglass and dull the finish.

Step 2

Rinse the tub or shower with warm water to avoid leaving any soapy residue behind.

Step 3

Dampen hard water or stubborn soap scum with white vinegar. Apply it directly to the stain with a spray bottle or a saturated cloth. After it soaks for at least five minutes, rinse it away with warm water.

Step 4

Mix baking soda and water into a thick paste to remove stains. Baking soda acts as a mild abrasive to help remove stubborn grime without scratching your tub.

Step 5

Dampen a cloth or sponge with nail polish remover -- make sure that it has acetone in it -- and scrub away tar, iodine and adhesive stains.

Step 6

Squeegee the shower or tub dry after cleaning to remove excess moisture and leave your fiberglass shower or tub looking shiny.
